The GameStop credit card comes with steep interest rate so the earlier you pay it off, the better it will be. Carrying a balance won’t do any good to your credit wallet and credit score. What matters is payment history and credit utilization ratio. The first should be without any missed or late payments. And the lower your credit utilization ratio, the higher your credit score. So, go ahead and pay off your credit card in one month. You can continue using your credit card and avoid interest payments if you pay off the card balance during grace period.
